What Is a Grid Generator?

CSS Grid is a 2D layout system: you declare columns and rows on the container, then items flow into the cells. Tracks can be fixed (`px`), flexible (`fr`), or auto-sized; `gap` adds spacing between them; `repeat()` and `minmax()` make responsive grids straightforward without a media query.

This generator gives you column and row sliders plus a live preview of the resulting grid. The generated CSS uses `repeat(n, 1fr)` for equal columns by default — a sensible starting point you can edit afterwards if you want a `200px 1fr 200px` sidebar shape, or `minmax(min-content, 1fr)` for content-aware tracks.

Frequently Asked Questions

What is CSS Grid?
Grid is a 2D layout system. Define rows and columns, place items in cells. Great for page layouts, card grids, dashboards.
fr vs px vs %?
fr is a fractional unit that splits remaining space proportionally — usually what you want. px is fixed. % is relative to the container.
How do I make it responsive?
Use fr units, minmax(), auto-fit/auto-fill. Or use media queries to switch column counts at breakpoints.
